<P>PROBLEM TO BE SOLVED: To provide a display apparatus in which image persistence on a display screen can be finely uniformized without showing up a portion of image persistence. <P>SOLUTION: Eight logic operation signals A(AND)B, A(OR)B, A*(AND)B, A*(OR)B, A(AND)B*, A(OR)B*, A*(AND)B*, and A*(OR)B* are generated by use of a NOT circuit 32, AND circuit 33 and OR circuit 34 based on two reference signals A, B having different frequencies from each other generating from a reference signal generator circuit 31. The eight logical operation signals are sampled by a reference clock to acquire one-bit data (eight data), and the eight data are assigned to the respective bits in a eight-bit data representing a gray scale value so as to generate a color signal of each pixel having a random gradation. <P>COPYRIGHT: (C)2007,JPO&INPIT |
